So glad you joined us. Arrival of baby chicks is so exciting and fun.
Do check out the learning center, especially on raising baby chicks and have all your equipment in place before they arrive. Decide on what starter feed you want to use and have it on hand as well. Upon arrival, they need to drink before they eat. Read about pasty butt, it is more common than I had expected. Check out the coop forums and get your plans ready. Try to start building once the chicks are in the brooder, it usually takes longer to get the coop ready than most of us expect.
Good luck, free free to ask questions, we're here to help.
